Vehicle Overview

The Mazda3 has been a sporty alternative for compact-car buyers since it debuted for the 2004 model year. It undergoes its first redesign for the 2010 model year and is still offered in sedan and four-door hatchback forms. The 2010 Mazda3 has all-new exterior and interior styling and is now available with a 2.5-liter four-cylinder engine that offers more power than the four-cylinder it replaces. Competitors include the Honda Civic, Ford Focus and Nissan Sentra.
